Write the mixed number as a percent 2 41/50

ehidna [41]

Answer:

∴ 2 $\frac{41}{50}$ = 282 %

Step-by-step explanation:

2 $\frac{41}{50}$

= [( 2 × 50) + 41] ÷ 50

= ( 100 + 41) ÷ 50

= $\frac{141}{50}$

=( $\frac{141 }{50}$ ) × $\frac{2}{2}$

= $\frac{282}{100}$

= 282 %

∴ 2 $\frac{41}{50}$ = 282 %

Write a conditional statement. Write the converse, inverse and contrapositive for your statement and determine the truth value o

photoshop1234 [79]

A conditional statement involves 2 propositions, p and q. The conditional statement, is a proposition which we write as: p⇒q,

and read "if p then q"

Let p be the proposition: Triangle ABC is a right triangle with m(C)=90°.

Let q be the proposition: The sides of triangle ABC are such that

$|AB|^2=|BC|^2+|AC|^2$ .

An example of a conditional statement is : p⇒q, that is:

if Triangle ABC is a right triangle with m(C)=90° then The sides of triangle ABC are such that $|AB|^2=|BC|^2+|AC|^2$

This compound proposition (compound because we formed it using 2 other propositions) is true. So the truth value is True,

the converse, inverse and contrapositive of p⇒q are defined as follows:

converse: q⇒p
inverse: ¬p⇒¬q (if [not p] then [not q])
contrapositive: ¬q⇒¬p

Converse of our statement:

if The sides of triangle ABC are such that $|AB|^2=|BC|^2+|AC|^2$
then Triangle ABC is a right triangle with m(C)=90°

True

Inverse of the statement:

if Triangle ABC is not a right triangle with m(C) not =90° then The sides of triangle ABC are not such that $|AB|^2=|BC|^2+|AC|^2$

True

Contrapositive statement:

if The sides of triangle ABC are not such that $|AB|^2=|BC|^2+|AC|^2$ then Triangle ABC is not a right triangle with m(C)=90°

True

In a survey of 248 people, 156 are married, 70 are self-employed, and 25 percent of those who are married are self-employed. If

MatroZZZ [7]

Answer:

The probability of selecting a person which is self-employed but not married equals 1/8.

Step-by-step explanation:

Here, the given survey says:

Total number of people surveyed = 248

Number of people married = 156

The number of people are self employed = 70

Now, 25% of people who are married are SELF EMPLOYED.

Now, calculating 25% of 156 , we get:

$\frac{25}{100} \times 156 = 39$

⇒ out of total 156 married people, 39 are self employed.

So, number of self employed people but not married

= Self employed people - Self employed people PLUS married

= 70 - 39 = 31.

So, the probability that the person selected will be self-employed but not married = $\frac{\textrm{The total number of people self-employed but not married}}{\textrm{Total Number of people}}$ = $\frac{31}{248} = \frac{1}{8}$

Hence The probability of selecting a person which is self-employed but not married equals 1/8.
